Wolfson Microelectronics plc WM2613
The WM2613 is a 12-bit voltage output, resistor string, digital-toanalogue converter. The DAC can be powered down under software or hardware control, reducing power consumption to 10nA. The device has an 8-bit microcontroller compatible parallel interface.FEATURES

● Dual 12-bit voltage output DAC Dual supply 2.7V to 5.5V operation DNL ± 0.4 LSB, INL ± 1.5 LSB Programmable settling time 1µ s or 3µ s typical 8-bit micro controller compatible interface Power down mode (10nA)
DESCRIPTION
The eight data LSBs, the four data MSBs, and the three control bits are written using three different addresses. Excellent performance is delivered with a typical DNL of 0.4 LSBs. The output stage is buffered by a x2 gain near rail-to-rail amplifier, which features a Class A output stage (slow mode, class AB). The settling time of the DAC is software programmable to allow the designer to optimize speed versus power dissipation. The device is available in a 20-pin TSSOP package. Commercial temperature (0° to 70°C) and Industrial temperature (-40° to 85°C) variants are supported.APPLICATIONS
